Mean sleep latency of the N−C patients with SOREM periods only from NREM1, NREM2 or both

N−C categorised by SOREM periods (n)MSL
SOREM periods only from NREM1 (11)*,**3±1.98
SOREM periods only from NREM2 (16)*,**4.9±1.94
SOREM periods from NREM1 and NREM2 (14)**3.55±2.2
  • *p=0.02 for N−C patients with SOREM periods only from NREM1 versus N−C with SOREM periods only from NREM2. ANOVA with post hoc test least significant difference was performed.

  • **p>0.05 for N−C patients with SOREM periods from NREM1 and NREM2 versus N−C with SOREM periods only from NREM1 or NREM2. ANOVA with post hoc test least significant difference was performed.

  • MSL, mean sleep latency; N+C, narcolepsy with cataplexy; N−C, narcolepsy without cataplexy; NREM, non-rapid eye movement sleep; SOREM, sleep onset rapid eye movement.
